The Boundaries of the Battlefield


Date: 10 & 11 January 2013

Venue: T.M.C. Asser Instituut, R.J. Schimmelpennincklaan 20-22, The Hague

On 10 and 11 January, ICCT together with the T.M.C. Asser Instituut convened a symposium on “The Boundaries of the Battlefield: A Critical Look at the Legal Paradigms and Rules in Countering Terrorism”. The event was organised in cooperation with the International Humanitarian and Criminal Law Platform, the Konrad Adenauer Stiftung, the Municipality of The Hague and the Dutch Ministry of Foreign Affairs. Twenty-eight legal experts from academia, civil society, governments, the military and multilateral organisations featured as panelists in this two-day symposium.

During the first two panels, the speakers discussed the temporal and geographical limitations of armed conflicts, followed by a panel focusing on the interaction between and possible complementarity of international humanitarian law and human rights law. The second day opened with a special panel on the legality of the use of drones and targeted killings. The symposium closed with sessions on the law enforcement approach in countering terrorism and a deliberation of the way forward, in particular, whether a new legal framework for counter-terrorism operations was necessary.

Many issues of both theoretical and practical nature were addressed and despite the often controversial character of topics debated, some common ground was found. One recurring issue was the legality of the use of drones by the United States outside the “hot

battlefields” of Afghanistan against alleged al-Qaeda members in such countries as Pakistan, Yemen and Somalia. The majority of participants concurred that drones as such are not an unlawful means of warfare, but that their current use may be not be in accordance with legal standards. Many participants believed that the concept of “naked self-defence” was counter-productive and that a new legal framework for armed conflicts against non-state actors was not needed. The participants agreed that such a third category of a “transnational armed conflict” would not add to the body of law that can be applied in conflict situations. This was mainly because fundamental principles of international humanitarian law – such as the threshold for the existence of an armed conflict, and the concepts of proportionality and necessity – would continue to apply as a matter of customary law. The speakers attributed some of the confusion in current discussions about legal frameworks in countering terrorism to the phenomenon of blurring the lines between the jus in bello and the jus ad bellum, which all urged to continue to keep separate for the proper application of the laws of armed conflict. In jus ad bellum terms, the speakers also largely agreed that a strict interpretation of the principle of imminence was necessary for the proper application of the inherent right to self-defence.

Overall, the symposium was considered a success, not least due to the innovative set up of the panel discussions: instead of consisting of individual presentations given by each panelist, a number of questions were directly debated between panelists with active input from the audience and moderators. The presence of such a diverse group of panelists and a lively audience of more than 70 individuals ensured that discussions were constructive. The Boundaries of the Battlefield symposium presented an important step forward in thinking about the legal aspects of counter-terrorism operations. On the basis of the discussions and conclusions of this meeting, ICCT Research Fellow Dr. Christophe Paulussen and Jessica Dorsey (Ph.D. Researcher at the T.M.C. Asser Institute) produced a comprehensive conference report.
